Lenovo Miix 320 external drive 500 gb without additional power

I watched many video reviews about Lenovo Miix 320, and all of them suggested that it is not possible for this small, but powerful little guy, to recognize and read external HDD without additional power... As you can see, it is possible, on ALL 3 USB ports (USB_A 2.0 and USB_C 3.1)... Stay tuned for more videos and reviews about this little beast :-)
